My invention relates to numbering chines and particularly to that classof'numbering machines which are automatioin their act-ion and whlch are usuallyso made that.

they permit the user to print numbers consecutively, or to print each number several times before the machine automatically changes one or more of the num'berln'g or type wheels to effect the printing of the next higher number upon the next. operation thereof, or

to repeat the printing of the same number over and over again. g

is constructed "and arranged so that itm'ay be set to repeat, to print consecutively, to dupllcate,the machine thus having; three different index settings and being what is commonly known a" "three inovement? machine. My invention, however, s sub ect to' variation in the direction just noted,al

though itris especially designed for appli cation to machines having but a small range of settings such'as to a three or four-move ment machine. I

- The present invention is especially designed for application to numbering machines of the type disclosed in my pending application Serial No. 174,298, fiied March 10,

1927, and in someaspects is an improvement on the invention described andclaimed in such application. j H

One of the objectsoi my invention is 'to provide in a numbering machine, an i111 proved control mechanism for the working pawl or equivalent device, which while quite similarin principle and operation to the control mechanism disclosed in my said pending application, has fewer parts of simplerlcon struction and is also preferably adapted to be adjusted or indexed directly to thereby change the machine to any desired setting.

Another object of my invention is to provide in a machine of the character described, simple and novel means for eiiectively. operating the working pawl, or equivalent device,

which actuates or advances the numbering ortype wheels; such means preferably comprising an oscillatory member'constitutlng a mountin for the t e wheels and within b V l re-inking, removal and replacement.

which the t pewh ei advancing device is substantially enclosed and thereby protected fronidust and damage from other causes.

Further-objectsotmy inventionare to provide a simple and elfectivearrangement for j properly'and positively aligningthe charac .ters or numbers of the type wheelslbefore each imprinting operation; to move the usual ink; pad frametowards and away from the printing or type wheels in'a novel manner; and to; provide a simple and effective 011- struc tion for locking the usual plunger "box carrying the type wheels and their actuating means,',1n a depressed position tothcreb'y hold the' ink pad frame ins'uch a position as: to i{ render the ink pad readily accessible for In general my invention resides in a numberin g machine which is not only less com-, plicated and less expensive to manufacture 7 than previous machines of a similar charac various mechanical forms, forpurposes erillustration the, preferred form asapplied to a three-movement numbering'machine of the type. disclosed in my said application Serial No. 1174,298, is shown in the drawings accompanying and forming 'part' of this specification, in which drawings,"

Referring to the drawings reference charlower ends of the legs of frame 1 and has an opening 3 through which the type of the nu mbering or type wheels project in'imprinting V or stamping the numbers. Reference character 4 represents a vertical stem or rod secured atits lower endto the numbering wheel head and extending; upwardly through at the center thereof, and also loosely through a cylindrical sleeve 5 having an enlarged or flanged lower annular end 5. The sleeve 5 is fixed to the top of frame 1 as by having its lower end 5 brazed thereto. The stem 1 has a handle or knob 6 secured to its upper end as by being threaded thereon, and said knob is provided with acylindrical axial recess 6 within which the upper end of sleeve 5 extends when the stem and numbering wheel head are in their uppermost or raised positions. A washer 7 is mounted on the shouldered upper end of the stem 4 at a point Some distance above the numbering wheel head, the stem 4 is provided with a notch 9 having a lower horizontal wall and an upper inclined wall, and mounted on the top of frame lis a slide 10 adapted to coact with said notch to lock the stem together with the numbering wheel head and the parts carried thereby in partially depressed position. The

in the slide with said notch.

slide 10 is in the form of a flat substantially rectangular piece of sheet metal having a central square opening 11 through which the stem 4: normally loosely extends, the sides ofsuch opening being slightly longer than the diameter of the stem. vThe slide 10 is supported from the top of frame 1 just beneath the same, by means of two upstanding T-shaped end projections 12 formed on the slide and respectively extending through T- shaped openings l in said top. It will be apparent that when stem 4; and the numbering head are depressed to a position in which the notch 9 is adjacent the slide 10, they may be effectively locked in such. depressed position merely by moving the slide 10 to the left, referring to Figs. 2 and 3, so as to engage a right-hand edge portion of the opening ll The ink pad carrier will then have been removed from the path of the numbering or type wheels, as will a slide 10 to the right, referring to Figs. 2 and 1 3, to non-locking position, and if the pressure is then removed from handle 6, the spring 8 will at once act to return the stem 4 and numbering wheel head to their uppermost or raised position. The heads of the *T-shaped end projections 12 of slide 10 are of such size that they will pass through the extreme right-hand end or head portions of the T-shaped openings 13 in the top of frame 1, but only through such portions of said openings, which construction renders i possible to easily apply the slide to the frame in assembling the machine.

The numbering wheel head or plunger box, indicated at 14, is in the form of a yoke or inverted U, and a barrel 15 having an axial cylindrical opening 15 extending therethrough, is mounted in a horizontal position between the legs or side members ofsaid head or box for oscillatory movement, by means of the short cylindrical slightly reduced sections 16 fixed to the ends of the barrel and journaled in suitable openings provided in said legs or side members. The sections 16, which may be considered as parts of the barrel 15, also serve to close the axial opening 15 at its ends, and are pro vided' with central reduced cylindrical projections 16 on their inner sides which extend into and fit closely within the end portions of said opening and thereby act to center the sections 16 when the latter are applied to the barrel, These cylindrical'end sectionsof the Q barrel are also providedcentrally thereof with reduced cylindrical portions or pins 17 which extend outwardlybeyond the sidesof the head 14 and into vertical guideways 18 ly closely in the uideways or slots 18, coact with the'litter to guide the head 14 in its reciprocatory movements in the mainframe.

The pins 17 respectively extend through actuating arms 20 which are disposed between the end sections-16 of the barrel 15 and the rollers l9 'and which are secured to said end sections "in the same angular relation thereto, as by screws 21, these sc'rewsalso dreds of thousands wheels. Other suitable:

main frame 1, and coact serving to rigidly secure the end sections 16 to the main body port-ion of thebarrel 1". The arms 20 are provided at their-outer ends with slots 22 which "are respectively'engage' by inwardly extending portions of members 23 rigidly secured, as by means ofscrews 24;, to the legs or side-members of'the stationary tooscillate the barrel 15 upon reciprocatory movement of the head lt in the frame 1.

. The type or numbering wheels 25, of which there are six in the machine illustrated, are

annular in form and are arranged side by' side within the yoke or head 14; and rotatably mounted on the barrel 15, these wheels being respectively theusual'units, tens, hun-:

dreds, thousands, tens of thousands and hunseries of wheels may be employed and the number of wheels used may, of 'course,also be varied as desired. The wheels25 are disfposed closely aajacen. each otherand a spacing ring 26 is loosely mounte'don' the barrel 15 between the numbering wheel of the highest order and the adjacent side member of the head 14. Reference characters 27 and 28 represent annular members comprising parts of my improved mechanismfor controlling the operation of the worming or stepped pawl, for various settings or said members being respectively. referred to herein as the control ratchet and the ratchet governor or control ratchetgovernor, The members 27 and'28 are rotatably mounted on the barrel -15, in the order named, between the units wheel 25 and the adjacent leg or side" member of the head or yoke i l, and are maintained in spaced rela t-ion by the hub or integral sleeve 29 with which the control ratchet 27 is provided, The members 27 and 28 are resiliently connected by means of a spiral flat spring 30 having its inner end secured to the hub 29 of member 27 and its outer end secured to a projection 31 which is provided on the member 28 at the outer edge of the latter and 'bering Wheels 25, as is customer nular edge thereof, these notches having tn the machine,

which extends laterally therefrom so as to lie in the path of, a. projection ortooth 32 formed on the outer edge ofthe control ratchet 27. The spring 301 constantly tends tomaintain the control ratchet 27in'such a position relative to the control'ratchet governor 28 that the tooth. or stop 32. o'njthe former will or that rotary movement ofthe control ratchet with respect to thefratchet governor to the age the lateral projection 31 i of the latter, and thearrangement is such '75 -ight, referring to Fig.6, thatv is, insuch y direction that t e tooth32 is moved away from the projection or stop .31 on the-ratchet governor will wind up or sion of the spring.

Each of the numj, provided withnine equi-spaced shallow notces 39 and a deep long notch 4:0 in rthelinner nusual disposition, i.v e., thereis one shallow 'notch 89 for each of-mne of the ten numbers on the wheel and the deep longnotcn a9 is employed for the tenth numberand for the purpose of carrying to the "wheel which.

low long notch 42 running into the deep notch 4C1. It will thus be apparent that the said inner periphery of numb-er 2? is for the greater part of its length, smooth or, un-

notched. The inner periphery of the ratchet governor 28, however, has no notches at all, being smooth for its entire length. The notch ,22 of the control ratchet 27 is of n n1- form depth for the greater portion of its latter notch, the bottom of said section length, the bottom of such portion beingformed on an arc concentric with the axis of the said ratchet, but for a purpose which will hereinafter be explained, such notch is provided with a, short section 18 adjacent the deep notch 11 which is of gradually increasing depth in a direction towards the thus being on a slight incline.

The main body portion of the barrel 15 is provided with a longitudinally extend g slotor cut-away portion 45extending inwardly from the surface ofthe barrel and intercepting the axial openin 15, and also, at its ends, with arcuate slots or recesses 425 which intercept the axial opening 15 and the slot 45. The working pawl comprises a pawl bar 4'4" having integral crank-arms l8 at its ends, a series of integral stepped pawls corresponding in numl er with and to coact respectively with the numbe ing wheels 25, and a sing e integral pawl or toot-l '50locatedlbetween the pawl 19 whichis A. i r m with its crank arms 18 disposed in the area ate recesses 46, and is pivotall supported .11 this position by means of pins 51fixed in are opposite end portions of the barreland having portions which extend into the recesses 4.6 and loosely engage aligned openings in said crank arms. The pawl bar 4'' of the working pawl as thus mounted, is adapted for inward and outward movements with respect to the axis of barrel 15, about the pins 51, and, with the machine assembled, is received in. the axial opening 15 and the lon tudinal slot 15 of the barrel. The said open ing 15 and slot l5 are of such size and shape as to accommodate the pawl bar 4:7 in all the various positions it assumes in the operation of the machine and thereby provide for proper coaction of the pawls l9 and 50 with the type wheels 25 and control ratchet 2*. 2rdjacent one end the barrel 15 is provided with an additional arcuate recess or slot 52 through which one of the pins 51 extends, and disposed in this slot and coiled about the said pin is a spring 53. The spring which is under tension, bears at one end a inst the barrel 15 and at the other end against the pawl bar 17, and therefore constantly tends to force the pawl barroutwardly aboutthe pivot pins 51 and into coacting engagement with the notched inner peripheries of the annular numbering wheels 25 and the control ratchet 27. 1

When the yoke or head 14 is reciprocatec in the main frame 1, the barrel 15 and thereby The the pawl bars? are oscillated to advance the numbering wheels by the usual step-by-step movements; it being understood, of course, that when the machine is set for duplicate the pawl bar will be held from coacting with and advancing the numbering wheels in every other reciprocation of the head 14, while when the machine is set for repeat the pawl bar will be continuously held from coacting with and'advancing the numbering wheels. As indicated above, such oscillatory movement is directly imparted to the barrel 15 and thereby to the pawl bar 17 upon the up and down reciprocatory movements of the head 14, by reason of the engagement of the members 23 carried by the stationary main frame 1, with the slots 22 of the actuating arms 20 carried by the barrel. The arrangement is such that the return movements or strokes of the pawl bar are effected upon the printing or down strokes of the head 14,.and the advancing or working strokes of the pawl bar are effected shallow working notch 4-2 in the control a; lo

notch 1-1 thereof is directly opposite the pawl 3&1 so as to be adapted to accommodate the latter. When the control ratchet is thus posltioned, the notch 41 therein permits the workpawl to engage the type wheels, and the said pawl will then, upon each of its working strokes, actuate or advance said wheels. Such workingstrokes of the stepped pawl will be referred to herein as actuating strokes.

The machine is provided, as is customary, with an ink pad frame 55 adapted to carry a pad (not shown) for inking the type or numbers of the wheels 25. The ink pad frame 55 is pivotally supported fromthe stationary main frame 1 by pins 56 (only one of which is shown) which extend through arms 57 provided at the opposite ends of the ink pad frame and into the adjacent side members or legs of the main frame. Movements of the ink pad frame 55 towards and away from the typewheels 25 about the pivot pins 56 are effected by the barrel 15 in the up and down and oscillatory movements of the latter, upon reciprocation of the head 14, through links 58 which are pivotally connected at their opposite ends respectively to the frame 55 and the barrel 15 by means of pins 59 and 60. The arrangement is such that as the numberin'g head 14 is reciprocated in frame 1, the ink pad frame 55, upon the down or printing movement of the head 14, will be moved outwardly by the barrel 15 about the axis of pivot pins 56 to that position in which the same is most remote from the wheels 25; while upon the up orreturn movement of the head, the said frame will be, moved inwardly by the barrel about the pins 56 so that upon the com:

plet-ion of such return movement apad can the control mechanism comprising the co'ntrol ratchet 27 and theratchet governor 28, such control; gechanism governing the action of the working pawl and being adapted when in as'etting other than the repeat setting to prevent actuation .or advancement of the numbering wheels by the working pawl until a' predetermined number of actuations of the machine and of working strokes of the working pawl. In the machine described herein the operative settings havepreferably.

been limited to three, namely: to consecutive, repeat and duplicate. The ratchet governor 28 is adapted to be moved about the axis of barrel 1"5-to andfirmly but yieldingly or releasably locked in any one of three angular positions corresponding respectively to the three settings of the machine. A desired index set-ting of the control mechanism and therebyof the machine is effected merely by moving the ratchet governor to the angular position thereof corresponding to such setting. The ratchet governor is provided with an elongated extension 62,- serving as an index lever, whereby the said governor may be positively and directly moved from any of said angular positions thereofto any other such position to thereby effect a change in the setting of the machine. A front plate 63 is secured as by screws 6e,to the head 14 and is R, D and C applied-to the front plate 63 adjacent said slot. The ratchetgovernor 28has three angular notches66, 6'? and 68 in its outer edge or periphery which respectively correspond in their location with the repeat, duplicate and consecutive posi tions or settings of the governor, and a'pawl 69 mounted on the rod 36 and constantly pressed towards said ratchet governor by a springarm'S'T, is provided with a rounded end arranged to engage that one of said notches corresponding to anyindex setting or position of'the governor to thereby yieldingly but releasably lock the latter in such position. In addition to the laterally extending projection or lug31, the ratchet governor i 28 isprovided at itsouter-edge with two simi-,

lar lugs 70 and 71, these three lugsbeing sub- I stantially equi-spa'cedand extending over or acrossf'the control .ratchet 27 to engage the outer face of theadjacentunits wheel25' for the purpose ofmaintaining the ratchet governorproperly spaced from suchwheel and prevent the same from interfering with the proper operation of the. control ratchet and the spring 30. y j

The periphery of the control ratchet 271s provided, in addition to the tooth or step 32, with a notch 72 one wall 73 of which extends 1n a substantially radial di rection' and provides an abrupt shoulder, and the other wall .or side 74 of which is in the'forinof 'a'lon'g cam surface inclining outwardly from the wall 3. andifinally merging in the main surface portion of the periphery of the ratchet. A retaining pawl 7 5 for the controlratchet 27 is pivotally 'inounted at one end on the rod 36, and a spring arm 37 rsecured to the head 14: bears against said pawl and constantly tends to force the same towards the control ratchet; This retaining pawl 75 is provided intermediate its endswith a tooth '76adapted to coact with the, notch 72 of the control ratchet, with a cam'77 between the tooth 7 6 and the pivot endthereof with which cam the spacer. or lugv 71 of the ratchet governor is adapted tocoact, iand with a notch 7 8 adjacent its free end and with which the spacer or lug 31 of the ratchet governor is adapted tocoact. A lever 79, which I shall refer to as a lift lever, is pivotally mounted at its lower end onla stud or pin'8O secured in and projecting from the adjacent leg or side member of the head 14, and a spring 81 coiled about said pinand having one end engaging a small opening 82 in said leg and the other end, bearing against said lever constantlytends to forcethe latter towards the control ratchet 27 and the lug 31 of the ratchet gov ernor 28.. The lift lever 7 9 has, intermediate the ends thereof, a cam portion 83 with which the toothj or projection 32 of-the control ratchet and the lug 31 of the ratchet governor are adaptedto coact; and at its upper end the said lift lever has an angular or laterally extending portion 84 adapted to coact withthe retaining. pawl 75.

Thespring arms '37, 37 and 37? which respectively'bear on th'e'pawls 35, 69 a'iidi75, are

preferably formed from a single resilient sheet metal-member and extend from a portion of such member secured to the top of the frame or head it by screws 38 (only one of i which is shown). For the purpose of better protecting and shielding its operating parts tings for which it is adapted will now be described: t

Repeat setting to this position the lug 31thereof engages the wall of the notch 78 inthe retaining pawl 75 and raises the latter to the position shown in full lines in Fig. 1, in which its tooth"!- 6 is wholly out of engagement with the V pee riphery of the control ratchet 27 and its free end is above and clears the upper angular end portion 8% of the lift lever 7 9. There upon the lift lever is moved by spring 81 into engagement with the periphery of control ratchet 27 and the spring 30 exerts an action tending to move the control ratchet in anticlockwise direction, referring to Fig. 6, to bring the stop or tooth 32 thereof into engagement with the lug 31 of the ratchet governor in the new position of the latter. Such movement of the control ratchet, however, is prevented or limited by reason of the engagement of the long tooth 0fthe working pawl 47 with the shoulder formed at the end of the long portion of the shallow notch 42 in the ratchet which is of uniform depth, and consequently the setting of the ratchet governor, as described, results in winding up or increasing the tension of the spring 30. If the machine is now repeatedly actuated the control ratchet is merely oscillated or moved back and forth, about its axis, with the working pawl 4i? and the barrel 15, and the tooth 50 of said pawl is constantly maintained in engagement with the shoulder at the end of the notch 42 in the control ratchet with the result that none of the numbering wheels 25 is advanced and the same number is therefore printed over and over. In this connection it is to be noted that whenever the longest tooth or pawl 50 of the working pawlengages the long portion of the notch 42 in the control ratchet, the working pawl is thereby held in a position inwardly of that in which any of the other teeth or pawls iSthereof would engage the inner periphery of any wheel 25. Nith the machine in this repeat setting none of the working strokes of the working pawl will be an actuating stroke. In each down stroke of the head 14: and the accompanying returnstroke of the working pawl, the control ratchet, under the action of the tensioned spring 30, turns in a direction to move the tooth or stop 32-thereof towards the lug 31 of the ratchet governor-28, and the shoulder at the end of the shallow notch 42 therein is maintained in engagement with the long tooth 50 of the Duplicate setting To now adjust the machine to its duplicate setting the indexing lever 62 is moved downwardly from the repeat position thereof to a position substantially midway between the ends of slot 65 and opposite the indication Wen the front plate (33. Such movement of lever "62 turns the ratchet governor. 28 to a position in which the notch 67 in the periphery of the latter is en -aged by the rounded end of the spring press pawl 69 and thus results in yieldingly locking the control mechanism in its new or duplicate setting. The lug 31 of the governor 28 is now in the position shown in Fig. 6 and accordingly does not act to prevent the retaining pawl 7 5 from moving, under the action of spring arm 3'7 into engagement with the periphery of the control rate iet 27. The arrangement is such that in this adjustment of the machine to its duplicate setting. the lift lever 79 is moved by its spring 81 into engagement with the edge of the ratchet at a point between the tooth or stop and the notch 72, before the pawl "55 is disengaged by the lug 31 of the govr ern r and thereby allowed to move inwardly suriicient distance to engage the tooth 76 hereof with said ratchet. The result is that the upper angular end portion 84 of the liftlever is positioned beneath the end of the re aining pawl so as to prevent the latter from moving inwardly to a position in which its teeth 6 is adapted to enact with the notch 72, and said end portion remains thus positicned until the lift lever 79 is moved outwai ilyby the tooth 32 of the control ratchet during the actuation of the machine in the new setting thereof, as will presently be de scribed. The adjustment of the machine to the duplicat setting, as well as to any other setting, is preferably effected when the ring head 1A- is in. its normalraised poshown in Figs. 1 and 2. The working 5 new at the end of a worki stroke l n long tooth or pawl 50 thereof in ement with the shoulder at the end of shallow notch 4-2 of the control "at 27, as shown in 6. Upon now ,ing tl e machine the cycle of operations 1 is as fclnws: On the first down-stroke of the J. V left, "efering to Fig. a

which the tooth TGhthereof engages thperiphery of the control ratchet at a po nt between the notch 72 and the tooth 32. 1 On the next or first upstroke of head 14, a work- 111;: stroke is imparted to the working pawl .47, but such workiiig stroke is not anactuating strol-:e and none of the numberingwheels advanced therein beeauseof thelo 51' tooth 50 ofthe workiuo' fact that the g a pawl in engagement with the long portion of the notch 42 of the ratchet 2'? throughouu ich stroke and all the remaining teeth or pawls thereby prevented from enp .ging the inner peripheries of the wheels with which they are respectively adapted to coact. in this working stroke of the pawl 47, however, the tooth 50 thereof engages the shoulder at the end of notch-42 the ratchet and moves the latteragainst the action of spring 30, thus restoring tension in such spring, to the position shown inl and the pawl 75 thereupon is moved inwardly still further by spring arm 37 andthe tooth 76 thereof 1s engaged with theinotch 72 of the ratchet. On the next or second down-stroke of head 14 the number set up on the wheels is printed a second time and a return stroke is. of course. linparted to the working pawl 47. In this return stroke of the working pawl. however, the ratchet 27 moves with said pawl, under the action of spring 30. only a short distance during the first part of such stroke, further movement of the ratchet being prevented by the engagement of the wall 73 of the notch 72 with the tooth 76 of the retaining pawl 75; during the last part of such return stroke the ratchet 2? is held stationary by the tooth 76, and the long tooth 50 of the working pawl rides over the bottom of the main portion of the shallow notch 42 in the ratchet 27,

'that such working stroke will be an actuating stroke. On the-next or second lip-stroke off iead 14 such anactuatingstroke is imparted to the working pawl 4Twhich, of course,results 1n the actuationor advancement of one or more of the numberlng wheels 25, depend:

ing on the number then set upon thewheels,

such actuation of each wheel thus advanced,

aswill'be understood, being effected by the 1 engagement. of one of the teeth 49 of the working pawl with one oft-he notches 39 and40 of the wheel. In this actuating stroke of the workingpawl (and this'is true of all actuating strokes of said pawl) the long tooth thereof also engages that" portion 'of the wall of the deep notch 41 in ratchet 27 which is adja'cent the long shallow notch 42. and turns said ratchet through such an angle to the right, referring to Fig. 6, with the numbering wheel or wheels being-advanced and against the action of spring 30, that the cain surface 7 4 forming one wallof then over the shortinclined portion 43 thereof and finally enters itheedeep'notoh 41. It is thus apparent that the working pawl 1s the notch 72 inthe ratchet acts on thevtooth r 76 of pawl (55 and thereby raises'tlie latter to a position in which the end thereof is clear of the upper angular endportion 84 of the lift lever 79. VVhenthe'pawl 7 5 isthus raised the lift lever 7 9 is moved by spring 81 to a position in whichits cam portion 83 engages the periphery of ratchet 27 at a point therein between the notch .72 and the tooth 32 a 1 and in which its angular end portion 84 is disposed beneath the free end of said pawland is adapted to maintain the latter in inoperative relation to the ratchet.

and nofurther change in position of any of the parts is effected, while'the duplicate setting is maintained, until the head 14 is given the first down-stroke in the next succeeding or second cycle of epera tionsof the machine.

The said; second cycle and every other succeed ng cycle of Qp6I a- B1O11S 1I1 this duplicate settlngofthe machine-differs from the first cycle of operationsjust described, only in the operations which are effected upon' the firstdown-stroke of the head 14 in such a succeeding cycle, and I shall now proceed to describe'in proper sequence the operations so effected. It is to be borne in mind that the working pawl 47 has just completeda working stroke, which was also an actuating stroke, in which it advanced one or more of the numbering wheels 25 and is now at the beginning of a'return strokewith each tooth 49 thereof which effected the advancinent of such wheel still engaging one of the notches in the inner periphery of the wheel,

7 The first cvcle of operations has now been completed andwith the long tooth 50 thereof engaging the wall of the deep notch 41 in the control r tchet 27at. a point adjacent the short incline-c section 43 of the shallow notch 42, thereby holding said ratchet in an angular position to the-right of that shown in Fig.

6 and in which the high portion of tl e long against the periphery of ratchet 27 at a point between thetooth 32 and the notch 72. Also. as is customary, the construction is such that each of the numbering wheels which has just been actuated was advanced to and is now in an angular position slightly beyond that in which the retaining pawl 35 for such wheel would engage one of the teeth of the ratchet 34 carried by the wheel. The down-stroke now being given to the head 14 by the depression of knob 6, the barrel 15 is, of course, turned to impart a return-stroke to the working pawl 47. In the very first part of this return stroke each wheel 25 actuated in the previous working stroke of the pawl 47, is, because of the engagement of a tooth 45) of said pawl with a notch on the inner periphery of the wheel, turned slightly in the opposite direction to that in which it was just advanced so as to bring such wheel into pr per alignment with he remaining wheels and the proper tooth of the ratchet 34 thereof into firm engagement with the retaining pawl 35 therefor. The pressure exerted by this spring-pressed retaining pawl 35 on the inclined rear face of an adjacent tooth of the said ratchet 34 also tends to turn the respective wheel 25 in the same direction and therefore assists in bringing such wheel into alignment, as will be clear from Figs. 1 and 4. I

Furthermore, the barrel 15 in the turning movement thereof which imparts the return stroke to the working pawl, also acts, by reason of its frictional engagement with the inside of said wheels, to align each of'the wheels 25 last advanced as well as any other wheels which may be out of alignment, and thereafter frictio nally acts to maintain all the wheels in proper alignment until the down-stroke of the head 14 has been completed and the number then set up on the wheels has been printed. The alignment of the wheels 25 is thus siinplyctiected and there is no occasion to provide any means other than the teeth 49 of pawl 47, to coact with the operating notches on the inside periphery of said wheels. Accordingly the said operating notches are made unusually wide with large contact surfaceswhich will result in longer life and improved action. Immediately after a wheel 25 last advanced has thus been brought into alignment, the pawl 47, through the c-oaction of one side or wall of an operating notch of such wheel with a pawl 49 as the return stroke of said pawl progresses, is moved inwardly about its pivot pins 51 to a position in which the said tooth 49 there-of is almost if not quite clear of the said operating notch, and in whichits long tooth 50 is withdrawn from the deep notch 41 of ratchet 27 and bears on the adjacent short inclined bottom section 43 of the long shallow notch 42. Thereupon the spring 30 at once acts to turn the ratchet 27 very rapidly to the left, refer ring to Fig. 6, until thesame is brought to a position where the shoulder at the end of the shallow notch 42 engages the tooth 50 of the pawl 47. The retaining pawl 7 5, however, is now prevented from engaging the ratchet 27 by the upper angular end portion 84 of the lift lever 7 9 as the latter still on gages the outer periphery of said ratchet at a point between tooth 32 and notch 72. In the said rapid movement of ratchet 27 the short inclined bottom section 43 of its notch 42 acts on tooth 50 of the working pawl and moves the latter inwardly still further about the pins 51 to a position in which all of the teeth 49 thereof are entirely free from engagement with the inner peripheries'of the wheels 25. The head 14 has now moved through but a small part of its down-stroke and the pawl 47 but a small part of its return stroke. 'As the down-stroke of head 14 is now continued, the pawl 47 continues to move in its return stroke about the axis of barrel 15 and the ratchet 27, under the action of spring 30, follows such movement of the pawl with the shoulder at the end of its notch 42 maintained in engagement with the pawl tooth 50. Shortly before the down stroke of the head 14 is completed the tooth 32 of ratchet 27 engages the cam section 88 of lift lever 79 and moves the latter about the pin 80 against the action of spring 81 to a position in which the upper end portion 84 thereof is clear of the free end of the retaining pawl 75, and the latter thereupon moves downwardly to a position in which its tooth 76 engages the periphery of the ratchet at a pointtherein between the notch 72 and the tooth 32. It will therefore be apparent that in the construction described the ratchet 27 acts automatically both to disengage itself from its retaining pawl 75 and to effect the re-engagement of said pawl with itselfsuch disengagement being effected upon a forward or advance movement of the ratchet and such re-engagement being effected upon a reverse movement of the ratchet under the action of spring 30. The number now set up on the wheels 25 is, of course, printed upon the completion of the down-stroke of head 14 and the return stroke of pawl 47.

In adjusting the machine to its duplicate setting from the consecutive settingthereof, the indexing lever 62 is merely moved up-v wardly in slot 65 of the front plate 63 from the position indicated by the character C to that indicated by character DU The rounded end of pawl 69 now engages the notch 67 in the ratchet governor 28 and yield-. ingly locks the control mechanlsm in proper position for the said duplicate setting. ASP the previous working stroke of pawl 47 W218 an actuating stroke'inwhich one or more of the numbering wheels was advancechthe pawl 47, ratchet 27 retaining pawl 75 and lift leverl79 are now in exactly the same positions they occupied at the beginning of the machine is changed to duplicate from consec'utive all the cycles of operations of the machine, including the first and every SL10- ceeding cycle, are similar in all respects and i are each identical with any cycle of operations, except thefirst, of the ma chine in the case where the latter has been changed from the repeat setting to the duplicate setting. i

Consecutive setting In adjusting the machine to its consecutive setting it is merely necessary to move i the index lever 62 downwardly in slot of setting of the machine.

the governor 2S thelugs 31' and 71 thereof respectively engage the cam portion 83 of the front plate 63, from either the repeat or duplicate positions thereof,to the position indicated by character C. Such movement of lever 62fturnzs the ratchet governor 28 to a position in which the rounded end of the pawl 69 engages the notch 68 in the governor and thus yieldingly locks the control mechanism in proper position for the consecutive In this position of lift lever 79 and thecam 77 of retaining pawl 75 and thereby hold said lever and pawl out of cooperative relation with thecentrol ratchet 27 in the positions shown in F g. .1.

The lug or stop 31:: of the governor 28Yis ment of theworking pawl 47 any return stroke thereof, only'a short distance before the tooth 32 engages said'stop or lug and such niovementof the ratchet is thereby arrested. Accordingly in this consecutive setting of the machine, upon each down-stroke of the in. such a position"thatthetocth -50"ofpawl 47 at or near the endof thea'c comoan i'n return stroke of the lattenienters the deep or clearance notch 41 of theratc'hetwith the result that at least one of the teeth 49hr said pawl is then adapted to engage an operating notch on the in'ner'periphery of one of the wheels 25 upon the working stroke of pawl 47 accompanying the following 11p-- stroke of the said head 14. It will therefore be apparent that each working stroke of-the machine will now be an actuating stroke effecting an advancement of one ormore of the wheels 25 and that the machine upon successive actuations thereof, will print consecutively.

The machine described isof simple and ru ged construction and the operation thereof. is accompanied by a minimum of wear.

li'lG-Sl? of the principal operatingtparts are effectively protected against injury. lnthis connectionit is to be noted that the working pawl is substantially entirely enclosed by the barrel and the numbering "wheels and other elements carried by said barrel; where- .by it practically impossible for dust or dirt to galn access to said its proper operation.
